Handheld Air Horns for Portable Power

Drill-Powered Performance & Smart Protection

The BossHorn handheld air horn pairs a high-output air compressor and real metal train horn trumpets with a custom control PCB to manage three volume levels, motor overheat protection, and battery deep-discharge safeguards. Our wireless remote lets you trigger the horn from up to 2,000 feet; no wiring or vehicle mounting needed. Hand-assembled in the U.S., each unit accepts OEM cordless tool batteries from brands like DeWalt or Milwaukee for instant, portable loudness and reliable runtime.

Designed for Use — Loud, Simple, Ready

This handheld air horn connects to standard tool batteries so you’re road-ready the minute you unpack it. Expect immediate, full-throttle sound for crowd control at events, clear warnings on work sites, and quick roadside emergency signaling. The tactile metal trumpets give a crisp, raw tone you can hear over noise, and the compact kit fits in a trunk or job-bag for fast access.

Durability, Battery Compatibility & Why It Matters

Looking for a handheld air horn that runs on DeWalt or Milwaukee batteries?

BossHorn is the first to make cordless drill-powered train horns with a wireless remote—so you can trigger from afar without installing anything. We build a custom control board into every horn for selectable volume and motor protection. BossHorn uses real metal trumpets salvaged from authentic equipment and pairs them with industrial-grade compressors. Each unit is hand-assembled in the U.S. and backed by a one-year warranty.
